The Study
Influence of Weight Reduction on Blood Pressure: A Meta-Analysis of Randomized Controlled Trials
This study looked at lots of experiments where people lost weight on purpose and found that, on average, their blood pressure went down. It’s like checking many different science projects and seeing the same result every time — so we can be pretty sure that losing weight helps lower blood pressure.
Analysis score
Maximum 100 for a systematic review with meta-analysis.
Where the score came from
When people lose weight, their blood pressure goes down — and the more they lose, the more it drops.

Key takeaways
Summary
Based on the study abstract and findings.
- 1These drops are clinically meaningful — similar to the effect of a single blood pressure medication, and enough to reduce heart attack and stroke risk.
- 2Losing 1 kg lowers systolic BP by 1.05 mm Hg and diastolic by 0.92 mm Hg.
- 3Losing more than 5 kg cuts systolic BP by 6.63 mm Hg and diastolic by 5.12 mm Hg.
- 4People on blood pressure meds saw even bigger drops.

Losing one kilogram of body weight lowers systolic blood pressure by about 1 mm Hg.
When adults lose one kilogram of body weight, their systolic blood pressure drops by 1.05 mm Hg and their diastolic blood pressure drops by 0.92 mm Hg.
In overweight adults with high blood pressure, losing exactly 5.1 kilograms through diet, exercise, or both reduces systolic blood pressure by 4.44 mm Hg and diastolic blood pressure by 3.57 mm Hg.
People who lose more than 5 kilograms experience larger decreases in both systolic and diastolic blood pressure than those who lose 5 kilograms or less, with the difference being clinically meaningful.
In adults taking blood pressure medication, losing weight lowers diastolic blood pressure by 5.31 mm Hg, which is a larger reduction than the 2.91 mm Hg seen in those not taking medication.
